Abstract

La présente invention concerne un module de reconnaissance d'empreintes digitales, un procédé de reconnaissance d'empreintes digitales et un écran de commande tactile. Le module de reconnaissance d'empreinte digitale comprend : un capteur optique, ayant une surface de réception configurée pour recevoir une lumière réfléchie par empreinte digitale; et un ensemble lentille, configuré pour faire converger la lumière réfléchie d'empreinte digitale vers la surface de réception du capteur optique, l'ensemble lentille comprenant une lentille à cristaux liquides, et la lentille à cristaux liquides étant configurée pour faire tourner les molécules de cristaux liquides à différents angles lorsqu'elle est mise sous tension afin de faire converger la lumière réfléchie par empreinte digitale vers la surface de réception du capteur optique. Au moyen de la solution technique d'un ensemble lentille convergeant la lumière réfléchie par empreinte digitale vers la surface de réception d'un capteur optique, le module de reconnaissance d'empreinte digitale, le procédé de reconnaissance d'empreinte digitale, et un écran de commande tactile prévu dans la présente invention augmente la quantité de lumière atteignant la surface de réception du capteur optique, et améliore ainsi la netteté du motif d'empreinte digitale optique formé, améliorant la précision de la reconnaissance d'empreintes digitales.
